6 dni temu · Use the formulas to calculate the circumference and area: c = 2πr and A = πr². The circumference should equal c = 2π × 8 cm = 50.265 cm. The area should equal A = π × (8 cm)² = 201.06 cm². To check your results, input the 8 cm radius in the calculator. The results should also be 50.265 cm and 201.06 cm².
How to Calculate the Area. The area of a circle is: π ( Pi) times the Radius squared: A = π r2. or, when you know the Diameter: A = (π/4) × D2. or, when you know the Circumference: A = C2 / 4π. Example: What is the area of a circle with radius of 3 m ? Radius = r = 3. Area = π r2. = π × 32. = 3.14159... × (3 × 3) = 28.27 m2 (to 2 decimal places)
